Heredity

A person that has only one mutated gene and one normal gene remains healthy but is a carrier, thus able to pass on the disorder to their children.

If both parents of a child are carriers:

• There is a 25% chance that the child will have sickle cell anemia.
• There is a 25% chance that the child will not carry any mutated genes at all.
• There is a 50% chance that the child will be a carrier.

---

If one parent has sickle cell anemia while the other parent is normal:

• All of their children will be carriers.

---

If one parent has sickle cell anemia while the other parent is a carrier:

• There is a 50% chance that a child would have sickle cell anemia.
• There is a 50% chance that a child would be a carrier.
